Container House Construction Technology

Container house construction technology involves dividing a complete building into standardized modules, completing the main structure, decoration, and equipment installation in the factory, and then transporting them to the site for assembly into a finished industrialized construction method. Its core processes can be divided into the following stages:

I. Factory Prefabrication Stage

1. Module Division and Production
   The building is divided into components such as the bottom, top, and four sides, and produced simultaneously through multiple sub-production lines. For example, a steel structure modular intelligent factory uses fully automated production lines, where welding, assembly, and grinding processes are completed collaboratively by robots. AGV (Automated Guided Vehicles) are responsible for material transportation, producing 50 modules per day with a manufacturing precision stable at 1-2 millimeters. The concrete MiC flexible production line produces a complete module every 20 minutes, equipped with 190 workstations and more than 80 professional pieces of equipment, achieving full-process automation from material input to finished module production.

2. Integrated Decoration
   Inside the modules, the main structure, pre-embedded water and electricity pipelines, bathroom waterproofing, bathroom fixtures, cabinets, and wardrobes are all completed during the decoration process. For example, connecting two containers can create a flat layout with an integrated living and dining area, two bedrooms, and a bathroom with a bathtub. Stacking them in a staggered manner can create richer spatial levels and leave a leisure courtyard or passageway area at the bottom.

II. On-site Assembly Stage

1. Foundation Construction
   Containers are elevated on pile foundations to achieve moisture and insect resistance and facilitate site leveling. Rural homesteads need to follow local requirements for building approval, providing structural drawings stamped by an engineer; arable land and basic farmland are strictly prohibited from construction; forest land requires forestry approval; leased land is mostly for temporary structures only, and the contract must clearly state the nature of use.

2. Module Hoisting and Connection
   Prefabricated modules are transported to the site using hoisting equipment and assembled using bolt connections or welding. For example, the concrete MiC production line in a smart construction industrial park in Shenzhen completes more than 70% of the construction processes in the factory, shortening the overall construction period by more than 60% compared to traditional construction methods.

III. Post-processing Stage

1. Facade Beautification
   The exterior facade is treated with paint spraying, themed spray painting, cladding, or glass curtain walls to shed the industrial feel and create a villa-like atmosphere. For example, installing large floor-to-ceiling windows, roof skylights, and glass partitions can enhance lighting effects, while adding internal insulation layers to walls/roofs and selecting triple-glazed windows can achieve warmth in winter and coolness in summer.

2. Performance Optimization
   To address the issue of limited net space in standard-sized containers, the building scale is expanded through adaptive combination design of the container bodies. For example, a 20-foot container can bear a load of 25 tons, a 40-foot container can bear 45 tons, the standard thickness of the side panels of a shipping container is 1.6 millimeters, and the roof panel is 2.0 millimeters, with different thicknesses customizable according to needs.
